Abstract

The effects of anthropogenic emissions of nitrous oxide (N2O), carbon dioxide (CO2), methane (CH4), and halocarbons on stratospheric ozone (O3) over the twentieth and twenty-first centuries are divided using a chemical model of the stratosphere. As halocarbon levels revert to pre-industrial levels, N2O and CO2 will likely play the primary roles in the evolution of ozone in the future. It is unable to distinguish clearly between these gases’ effects on ozone due to nonlinear interactions between them. The work was conducted using the monthly and annual data of the gases in the stratospheric layer to determine the overlap between N2O and O3 for the Iraq station and for the period (2003-2016). The strength of the association between gases was determined using the Spearman rho test (rs). It was found that there is a very high positive relationship between the N2O and O3 in Nasriyah station, which is 0.807 which indicates a strong association. This is because meteorological conditions, climatic fluctuations, and atmospheric location all affect correlation. The ozone layer is destroyed by nitrous oxide at high concentrations through the stratosphere layer and the tropospheric layer, the concentration of ozone increases with an increase in the concentration of nitrogen dioxide.

臭氧消耗潜能值加权人为氧化亚氮排放量的影响

利用平流层化学模型划分了二十世纪和二十一世纪人为排放的一氧化二氮（N2O）、二氧化碳（CO2）、甲烷（CH4）和卤代碳对平流层臭氧（O3）的影响。随着卤烃含量恢复到工业化前的水平，N2O 和 CO2 将可能在未来臭氧的演变中发挥主要作用。由于这些气体之间存在非线性相互作用，因此无法明确区分它们对臭氧的影响。这项研究利用平流层气体的月度和年度数据，确定了伊拉克站和期间（2003-2016 年）N2O 和 O3 之间的重叠情况。使用斯皮尔曼 rho 检验（rs）确定了气体之间的关联强度。结果发现，Nasriyah 站的 N2O 和 O3 之间存在很高的正相关关系，即 0.807，这表明两者之间存在很强的关联。这是因为气象条件、气候波动和大气位置都会影响相关性。高浓度的一氧化二氮通过平流层和对流层破坏臭氧层，臭氧浓度随着二氧化氮浓度的增加而增加。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
